The survey of literature attempts to do an analysis of a very large number of Neo-Scholastic philosophers around the world.
The survey includes those who were, at minimum, trained in the Neo-Scholastic tradition during the twentieth century, or those
who were the founders of Neo-Scholasticism slightly prior to the opening of the twentieth century. Names of authors are listed
as found on the title pages of their books. Footnotes with major bibliographical information were listed in this chapter,
but verification of the every position of each author on evolution is found in the appropriate chapter in the synthetic part
of this dissertation, to avoid repetition of the same notes and to place notes where the actual debate about proofs is located.
Listing of the 120 Neo-Scholastics was done geographically and chronologically, with some adaptations.

Geographically, listing by country or linguistic area is a reasonable attempt at classification. Since an
alphabetical listing of over one hundred philosophers would be very cumbersome, this listing gathers philosophers by similar
geographic area or linguistic area, except for some special cases: those teaching at the Gregorian University in Rome, secondly
for those teaching in Rome at the various pontifical universities and academies, and third for popes trained in scholastic
philosophy but actually resident in the Vatican. The listing by language groups was an attempt to allow comparison, in the
event this might be possible. Of course, some authors wrote in Latin at one time and in a modern language at another time.
A reasonable attempt was also made to classify geographically the more international subjects of this study, such as Teilhard
de Chardin, who was trained in France, worked in China, and died in the United States. Another example of internationalism
is Ivan Illich, who was scholastically trained in Rome, obtained a doctorate in Vienna, was active as a priest in New York,
was an educator on the island of Puerto Rico, and finally opened a school of Spanish culture in Mexico.

Chronologically, this listing of philosophers includes those who have lived in the twentieth century or influenced the
beginning of Neo-Scholasticism in the early twentieth century. The dates listed next to the names of the philosophers are
usually the dates of publication of their more recent major works. The reason for this method of dating is an attempt to show
the interrelation of philosophers who might have influenced each other, and to show the continued influence of the Neo-Scholastics
even to the end of the twentieth century
